INVENTOR F. G. SCHLOSSER United States Patent 3,458,184POSITIONER-ALIGNER STRUCTURE FOR ANCHOR BOLTS Francis G. Schlosser,Ridgefield Park, N.J., assignor to Pfaif and Kendall, Newark, N.J., acorporation of New Jersey Filed Apr. 3, 1967, Ser. No. 627,954 Int. Cl.B23q 3/18; A47j 47/16; A45d 19/04 U.S. Cl. 269-287 3 Claims ABSTRACT OFTHE DISCLOSURE A positioner-aligner for holding anchor bolts inregistered plumb position in an excavation at a grade, while theconcrete is being poured and sets in the excavation, accuratelypositioning the bolts in true plumb relation, said aligner being formedof a flat planar sheet which may be folded to define thepositioner-aligner and providing a strong and rigid structure.

This invention is concerned with the problem of securing lighting andtrafiic poles and other structural forms to grade surfaces. It iscustomary to provide an excavation at the site of proposed installationof the pole. Anchor bolts are keyed or secured to the grade on pouringcement into the excavation with the anchor bolts extending partiallyfrom the excavation.

Heretofore various makeshift arrangements were used for holding thebolts in place while the concrete is being poured and sets.

Hereto fore, contractors used wood forms with holes therein or wire tiedto hold the bolts in place. These methods are not always successful inthat bolts are thereby not positioned accurately and sometimes they alsocock at an angle so that they are no longer plumb. Such hit or missmethods are inaccurate and result in position misalignment on setting ofthe concrete. It is imperative, for most purposes, that the anchor boltsbe accurately plumb and parallel to assure the true perpendicularalignment of the pole, etc. at the site.

This invenion assures the positioning of the anchor bolts precisely inthe desired predetermined spaced relation and at the proper height abovethe grade and also assures their being so maintained and truly plumbwhile the concrete is being poured and sets.

Advantages of the device of the invention are:

(1) Material is cardboard and is very economical.

(2) Can be shipped flat.

(3) Folds into twin structural channel shapes which are rigid andstrong.

(4) Bolt holes position bolts accurately at proper height above grade.

(5) Each bolt goes through two holes equally spaced and thus cannot cockofi plumb while concrete is being poured.

Pursuant to the invention, strength and rigidity are obtained frominexpensive, weak, non-rigid materials such as cardboard, by foldinginto structural shapes that resist bending and are stiff because of thebeam action inherent in shapes of this nature.

The positioner-aligner of this invention may be stored flat inquantities, in limited space, and may bereadily fabricated .at the siteto interlock and accurately assemble the bolts at precisely the desiredposition and spacing at the grade during the concrete pouring operationand setting operation and may thereafter be readily disengaged from thebolts and restored to flat, foldable position for storage or reuse.

The drawings, illustrating procedures and devices useful in carrying outthe invention, and the description below, are exemplary only of theinvention, which shall be deemed to cover all other devices andprocedures coming within the scope and purview of the appended claims.

In the drawings, wherein similar reference characters indicate likeparts:

FIG. 1 is a perspective view of a positioner-aligner embodying myinvention,

FIG. 2 is a side elevational, partly sectional view, showing thestructure as used and holding anchor bolts in registered plumb positionin an excavation at a grade, while the concrete is setting, and

FIG. 3 is a top plan view of the said positioner-aligner in initial,planar form, prior to being folded to its FIGS. 1 and 2 structural form.

Pursuant to the invention, the positioner-aligner is fabricated of aflat planar sheet 10 which may be made of various lengths and heightsfor various sized bolt circles and mounting configurations. The sheet 10may be made of any readily foldable material, scored or ruled to definea center web portion '11 and side portions 12 extending from the centerweb portion, prefer-ably along parallel score lines 13 so as to bereadily foldable downward- 1y to form the sides 12 (FIG. 1). The centerweb portion has a concrete pouring opening 14 formed therein mediallyfor the pouring of concrete 15 (FIG. 2) therethrough and into theexcavation 16 at the grade 17 at the site at which a pole or otherstructure is to be secured, by anchor bolts 18 to be positioned, by thepositioner-aligner of this invention, in parallel plumb spaced andpredetermined relation to the grade 17, during the pouring and settingof the concrete 15.

Portions 12, after being so folded downwardly into parallel spacedrelation, defining the side walls (FIG. 1) are re-entrably inwardlyfoldable vas at 19 (FIGS. 3 and 1) to define bottom flanges 20 parallelto the center web portion. Said center web portion and bottom flangeshave aligned apertures 21-21, 22-22, 23-23, 2424, to receive andmaintain the bolts 18 positioned in plumb aligned spaced relation whilethe concrete is so poured through aperture 14 and sets. The center webportion has extended end flanges 30, 31 'formed thereon intermediate theside wall portions, preferably foldable along score lines 32, 33, tofold the end flanges 30, 31 down- Wardly (FIG. 1) and define end walls.Complementary interlocking means are preferably provided on the endflanges and side walls. The side portions 12 may be extended beyond thebottom flange portion thereof to define inner side walls 34, 35 onfolding said extended portions upwardly and parallel to the side wallportions 12, preferably along the score lines 36, 37. The inner sidewalls 34, 35 are thus foldably upwardly parallel to the side wallportions 12 and in spaced relation thereto and have registrationengagement with end walls 30, 31. Any suitable interengaging means maybe provided for interlocking the inner side walls and the end wallsforexample (FIG. 3) by providing slitted portions 38, 39 on the end wallsfor interlocking reception of the inner side walls 34, 35.

If desired, the end walls may be received in the slotted portions 40, 41of the inner side walls 34, 35 or said slitted portions 40, 41 may becomplementary to the slitted portions 38, 39 of the end wall flanges 30,31.

As the bolts pass through the aligned apertures 21- 21, 22-22, 23-23,2424', they are held true and parallel and cannot go off plumb while theconcrete is being poured and set. The web portion 11 is essentiallykeyed to the dual beam body structure, forming, with the parts 34, 2t 12one longitudinal beam, and the parts 12, 20, 35 a second longitudinalbeam in a structure which may be made of light, relatively weakmaterials, form- While the foregoing disclosure of exemplary embodimentsis made in accordance with the Patent Statutes, it is to be understoodthat the invention is not limited thereto or thereby, the inventivescope being defined in the appended claims.

I claim:
